Until it is measured, not known. Yet how you miss it when it has gone. What is it?

Below, you can see some coding:
January = 1017
February = 628
March = 1335
April = 145
May = 1353
June = 1064

Now deciphering the way it has been coded, can you find out how September will be coded?

In a university, a professor gave a set of three problems to the three brilliant students of his class. See the image for the questions.

I have 50 feet long of cloth, I need to create 50 handkerchiefs each size of 1 foot. I take one minute to cut a 1-foot handkerchief. So how long will it take to cut 50 handkerchiefs?

Different lights make me strange by changing me into different sizes. What am I?

If,

6 / 7 = 2
3 / 9 = 7
8 / 2 = 6

Then

4 / 5 = ?
